Talosaga o Mea:
1. I le faʻaopoopoga i le faʻaogaina o meaola, o lenei oloa o loʻo faʻaaogaina lautele e pei o le cellulose acetate film, cellulose triacetate pumping, petroleum dewaxing, solvents i le gaosiga o aerosol ma vailaau faʻamaʻi, vitamini, vailaʻau faʻamaʻi, faʻapea foʻi ma le faʻamamaina o le lacquer ma le degreasing ma aveese ata.
2. Faʻaaogaina i le fumigation saito ma le pusaaisa o pusaaisa maualalo-omiga ma iunite malulu. Fa'aaogaina e fai ma sui feula fesoasoani i le gaosiga o le polyether urethane foam ma avea ma sui feula mo extruded polysulfone foam.
3. Faʻaaogaina e pei ole solvent, extractant ma mutagen. Fa'aaogaina i su'esu'ega fa'atupu o la'au.
4. O loʻo i ai le solvency lelei, o se mea faʻapipiʻi maualalo maualalo ma le itiiti o le oona ma le le mafai ona mu i totonu o soʻo faʻaoga masani, ma e lelei le solvency mo le tele o resini, paraffins ma gaʻo. E masani ona faʻaaogaina e pei o le vali vali, suauʻu dewaxing solvent, extractant of thermally unstable substances, extractant of lanolin from wool and edible oil from coconut, solvent of cellulose triacetate film. Fa'aaoga lautele foi i le acetate fibre, vinyl chloride fiber gaosiga, gaosiga ma afi afi, refrigerants, urotropine ma isi gaosiga.
5.Used i alamanuia faaeletonika. E masani ona faʻaaogaina e fai ma mea faʻamamā e aveese ai le suauu.
6.Widely faʻaaogaina e avea o se mea e faʻafefe ai le afi ma se mea e faʻafefeteina ai. I le faaopoopo atu i le fufuluina o solvents mo afi vaalele, masini saʻo, ma isi mea, e mafai foi ona faʻaaogaina e avea o se mea e faʻafefe ai vali, ma e mafai foi ona faʻafefiloi ma isi solvents e faʻaaogaina i le tele o fale gaosi oloa.
7.Also fa'aaogaina e pei o le ethyl ester fiber solvent, nifo fa'apitonu'u fa'apitonu'u, refrigerant ma afi tineia sui, ma isi, o se eluent masani mo chromatographic separation ma le aveeseina o le vavaeeseina masani.
